ABSTRACT:

Introduction

Insomnia is common, but access to its first-line treatment, cognitive behavioral therapy for insomnia (CBT-I), is limited. To explore a scalable alternative, we investigated the efficacy of sleep restriction therapy (SRT), a core component of CBT-I, delivered via telephone.
